1, boiler capacity, that is, output q, and the unit of steam boiler is expressed in tons/hour. The hot water boiler is expressed by the heat supply MW/h;

2. Pressure p, in MPa;

3. Steam (or superheated steam) temperature q, in degrees Celsius. Expressions of outlet temperature and backwater temperature of hot water boiler. In addition, there are heating surface area, grate area, fuel type, fuel consumption, water supply temperature, total wind resistance, airflow distribution (induced by blowing) and exhaust temperature.

Model description includes: number of drums (such as single drum D, double drum S, etc. ); Roller layout (horizontal H, vertical Z); Combustion mode (chain L, fixed grate G, etc. ); Fuel type (coal A, gas Q, fuel Y, etc. );
